High-accurate Fourier-transform infrared spectra of C2D4 were recorded and analyzed in the region of 600-1150 cm-1 where the bands ν7(B1u), ν10(B2u), ν12(B3u) are located as well as the ν4(Au) band which is forbidden by the symmetry of the molecule. The ground state rotational structure was re-analyzed by the use of ground state combination differences obtained on the basis of infrared transitions of the ν12 and ν7 absorption bands. This gave us the possibility to considerably improve the rotational and centrifugal parameters of the ground vibrational state. The analysis of the experimental data and the subsequent weighted-fit procedure of the Hamiltonian parameters allowed us to reproduce the initial 4405 "experimental" ro-vibrational energy values with the drms=2.1×10-4cm-1.
